## Questions & Answers

**Q: Does anyone have experience with how this will work in high heat conditions such as 100 deg. F, high humidity and direct sunlight on the doors/jamb?**
A: I used this on my car which sits out in direct Texas sunlight every day. Seems to be good so far.

**Q: would this help prevent my neighbors smoke from coming through my front door if i put it around my front door?**
A: yes, if properly installed

**Q: If I install this on my apartment door, can I smoke inside and not worry about the smell seeping into the building hallway?**
A: this item is great for the sides and top, but i would recommend you to quit smoking than there wouldn't be smoking anywhere to worry about.

**Q: I've got a couple really smalls gaps in an outdoor shed between the door and frame. Will this close them up to keep out bugs and the weather?**
A: Depends on the gap and how flush the finish of each part is. Should work for nominal weather stripping, but will not replace flashing above a door to keep water out directly.
